A quantum computer could potentially solve some problems more efficiently than any classical computing device. Of the oft-quoted potential uses, the most important is likely to be the simulation of quantum systems by a quantum computer. However, errors are still the greatest obstacle to building such a device. There are several methods for protecting information encoded in quantum states from noise. They include quantum error correcting codes, decoherence-free or noiseless subsystems, and dynamical decoupling controls. These methods to prevent errors will be discussed, as well as some of the latest projects and problems encountered in this area of research.
